Final answer:
All controlled products, including waste, should be labeled unless the chemical in the waste is unused and is a commercial chemical product. High-voltage wires are not wrapped in insulating material, and wave-particle duality does not apply to macroscopic objects.
Step-by-step explanation:
The statement that all controlled products used, handled, or stored at a workplace must be labeled except for wastes to be discarded is false. Controlled products, even if they are intended to be waste, should be appropriately labeled to ensure safety and proper handling until their disposal. However, the chemical in the waste must be unused and must be in the form of a commercial chemical product for it not to require labeling.
For the second statement, it is false that high-voltage wires connected to tall metal-frame towers are held aloft by insulating connectors and are wrapped in insulating material. While the connectors are indeed insulating to prevent electrical discharge to the towers, the high-voltage wires themselves are typically not wrapped in insulating material due to the complexity and expense of insulating high-voltage transmission lines.
The statement on wave-particle duality is false. Wave-particle duality is a concept in quantum mechanics that applies to particles at the atomic and subatomic scale, but not to objects on the macroscopic scale.
